Description
本発明は、衛生が要請される環境の殺菌や洗浄を行う方法、殺菌システム、洗浄システム、殺菌洗浄システム、およびそれらシステムの製造方法に関する。 The present invention relates to a method for sterilizing and cleaning an environment where hygiene is required, a sterilization system, a cleaning system, a sterilization cleaning system, and a method for manufacturing the system.
衛生が要請される製品を製造する際には、製品の容器の殺菌、容器への内容物の充填、蓋の取り付け等の処理が行われる環境の殺菌、洗浄が必要である。
そういった環境を区画するチャンバの壁面や、チャンバ内に配置された容器の搬送装置および充填ノズル等の設備を含め、チャンバ内の全体が、所定時間、殺菌剤を散布することで殺菌される(特許文献1)。チャンバの壁面や、製造設備に付着した殺菌剤は水を用いることで洗い流される。
チャンバ内に散布された殺菌剤は、タンクに回収して再度チャンバ内に送るように、循環させることができる。
When manufacturing a product that requires hygiene, it is necessary to sterilize and clean the environment in which the container of the product is sterilized, the contents of the container are filled, and the lid is attached.
The entire chamber is sterilized by spraying a disinfectant for a predetermined time, including the wall surface of the chamber that partitions such an environment, and equipment such as a container transfer device and a filling nozzle arranged in the chamber (patented). Document 1). The disinfectant adhering to the walls of the chamber and the manufacturing equipment is washed away by using water.
The disinfectant sprayed in the chamber can be circulated so that it can be collected in a tank and sent back into the chamber.
容器の殺菌、容器への充填、蓋の取り付け等の処理が行われる環境は、一般に、処理工程に応じて複数の区画に区分されている。これらの区画を殺菌、洗浄するため、典型的には、図8(a)に示すように、タンク101と、送り用のポンプ102と、戻り用のポンプ103とを使用し、複数の区画A〜Cの殺菌と洗浄を順次行う。
例えば、区画Aを殺菌する際には、タンク101内に貯留されている殺菌剤をポンプ102により区画Aへと送ってノズル104Aから区画A内に散布する殺菌を開始し、タンク101から所定の量だけ区画Aへと送られたならば、ポンプ103を作動させて区画Aの底部に溜まった殺菌剤をタンク101へと戻し、タンク101と区画Aとの間で殺菌剤を循環させながら、所定時間に亘り殺菌を行う。この殺菌が終われば、区画A内から殺菌剤を排出させてタンク101へと回収する。
The environment in which processing such as sterilization of a container, filling of a container, and attachment of a lid is performed is generally divided into a plurality of sections according to the processing process. In order to sterilize and clean these compartments, typically, as shown in FIG. 8A, a tank 101, a feed pump 102, and a return pump 103 are used, and a plurality of compartments A are used. ~ C is sterilized and washed in sequence.
For example, when sterilizing the compartment A, the sterilizing agent stored in the tank 101 is sent to the compartment A by the pump 102 to start sterilization to be sprayed into the compartment A from the nozzle 104A, and a predetermined sterilization is started from the tank 101. When only the amount was sent to the compartment A, the pump 103 was operated to return the disinfectant accumulated at the bottom of the compartment A to the tank 101, and while circulating the disinfectant between the tank 101 and the compartment A, Sterilize for a predetermined time. When this sterilization is completed, the sterilizing agent is discharged from the compartment A and collected in the tank 101.
以上で区画Aの殺菌工程が終われば、区画Bの殺菌工程へと移行するため、バルブ105Aを閉じてバルブ105Bを開き、タンク101から区画Bへの送液を開始し、上述と同様、タンク101と区画Bとの間で殺菌剤を循環させながら、所定時間に亘り殺菌を行う。それを終えて殺菌剤をタンク101へと回収したならば、区画Cについても同様の殺菌工程を繰り返す。 When the sterilization step of the compartment A is completed, the valve 105A is closed and the valve 105B is opened to start the liquid feeding from the tank 101 to the compartment B in order to shift to the sterilization step of the compartment B. Sterilization is performed for a predetermined time while circulating the disinfectant between 101 and compartment B. After that, when the disinfectant is collected in the tank 101, the same disinfection step is repeated for the section C.
図8(a)に示す方法によれば、先に殺菌が開始された区画からの液の排出を待って、次の区画の殺菌へと移行するので、最初の区画の殺菌を開始してから、最後の区画の殺菌を終えるまで、区画の数に応じた時間を要する。 According to the method shown in FIG. 8A, the process proceeds to the sterilization of the next section after waiting for the liquid to be discharged from the section where the sterilization was started first, so that the sterilization of the first section is started. , It takes time according to the number of compartments until the sterilization of the last compartment is completed.
水を用いて区画A〜Cを洗浄する場合は、水を貯留するタンクから、まず、区画Aへと水を供給してノズル104Aから所定時間に亘り散布しつつ、溜まった水を区画Aから排出させながら区画A内を洗浄する。 When cleaning compartments A to C with water, first, water is supplied from the tank for storing water to compartment A and sprayed from the nozzle 104A for a predetermined time, and the accumulated water is sprayed from compartment A. The inside of the compartment A is washed while being discharged.
以上で説明したように、殺菌や洗浄を複数の区画について順次行うと、複数の区画の数の分だけ、環境の殺菌や洗浄に要する時間が積算される。
一方、図8(b)に示すように、タンク101´から区画A〜Cに同時に殺菌剤を供給すると、区画A〜Cの殺菌工程が並行して行われるので、環境の殺菌に要する時間を短縮することができる。
As described above, when sterilization and cleaning are sequentially performed on a plurality of compartments, the time required for sterilization and cleaning of the environment is accumulated by the number of the plurality of compartments.
On the other hand, as shown in FIG. 8B, when the sterilizing agent is simultaneously supplied from the tank 101'to the compartments A to C, the sterilizing steps of the compartments A to C are performed in parallel, so that the time required for sterilizing the environment is increased. It can be shortened.
その一方で、区画A〜Cに同時に散布可能な量の殺菌剤をタンク101´に用意する必要があるため、区画A〜Cを順次殺菌する場合(図8(a))と比べてタンク101´が大型化し、殺菌剤の使用量が多いためコストが増加する。
しかも、区画A〜Cに同時に殺菌剤を所定流量で循環させることのできる能力の大きいポンプ102´,103´が必要となる。区画A〜Cに殺菌剤を循環させる主要な配管106,107として、殺菌剤の必要流量に見合う大径の配管も必要となる。
On the other hand, since it is necessary to prepare an amount of a disinfectant that can be sprayed to the compartments A to C at the same time in the tank 101', the tank 101 is compared with the case where the compartments A to C are sequentially sterilized (FIG. 8A). ´ becomes larger and the amount of disinfectant used is large, which increases the cost.
Moreover, pumps 102'and 103'with a large capacity capable of simultaneously circulating the disinfectant at a predetermined flow rate are required in the compartments A to C. As the main pipes 106 and 107 for circulating the disinfectant in the sections A to C, a large diameter pipe corresponding to the required flow rate of the disinfectant is also required.
水を用いる洗浄の場合も、区画A〜Cの洗浄工程を並行して行うことにより、洗浄に要する時間を短縮することができるが、タンクが大型化し、ポンプの能力増強および主要配管の大径化が必要となる。 In the case of cleaning using water, the time required for cleaning can be shortened by performing the cleaning steps of compartments A to C in parallel, but the tank becomes larger, the pump capacity is increased, and the diameter of the main piping is increased. It is necessary to change.

The self-circulation system 3 does not extend to the tank 11 away from compartments A to D and is routed near the corresponding compartment.
The main feature of the present embodiment is that the sterilization step of sterilizing compartments A to D and the washing step of washing compartments A to D with water include a self-circulation step.
自己循環系統3が形成する「区画を含んで閉じた経路」は、供給系統12による当該区画への液(殺菌剤または水)の供給、および当該区画からの液の排出がいずれも断たれた状態で環状に構成されている。
例えば、導入バルブ12vAと、戻りバルブ153Aとがいずれも閉じられていると、自己循環系統3Aが閉じた経路を形成している。
自己循環系統3は、殺菌システム10および洗浄システム20の両方に使用される。
In the "closed path including the compartment" formed by the self-circulation system 3, the supply of the liquid (bactericide or water) to the compartment by the supply system 12 and the discharge of the liquid from the compartment were both cut off. It is configured in a ring shape in the state.
For example, when both the introduction valve 12vA and the return valve 153A are closed, the self-circulation system 3A forms a closed path.
The self-circulation system 3 is used for both the sterilization system 10 and the cleaning system 20.
自己循環系統3Aは、対応する区画の外に排出される殺菌剤または水を受け入れて対応区画の内へと導く循環用経路31Aと、循環用経路31Aを通じて殺菌剤または水を圧送することに兼用される上述の戻りポンプ152Aと、循環用経路31Aを開閉可能な循環用バルブ32Aとを含んで構成されている。

例えば、導入バルブ12vAおよび戻りバルブ153Aが閉じられ、循環用バルブ32Aが開かれていると、自己循環系統3Aを通じて区画Aの内と外とを殺菌剤または水が循環する。
The circulation path 31A is connected to the introduction path 12A corresponding to the same section A, and the introduction valve 12vA and the circulation valve 32A are used to send liquid to the section A through the introduction path 12A. , Self-circulation through the self-circulation system 3A can be switched.
For example, when the introduction valve 12vA and the return valve 153A are closed and the circulation valve 32A is open, the disinfectant or water circulates inside and outside the compartment A through the self-circulation system 3A.
区画A〜Dに要求される所定の殺菌能力に基づいて、必要な殺菌剤の量、流量、および殺菌時間が決まる。
また、使用された殺菌剤を区画A〜Dの壁や、搬送装置の部材、充填バルブ等から十分に洗い流して除去、あるいは殺菌剤の濃度を閾値未満に下げることができるように、洗浄に必要な水の量、流量、および洗浄時間が決まる。
全ての区画A〜Dについて所定の殺菌能力および十分な洗浄能力を得ることができるように、各区画A〜Dの広さや各区画A〜Dに配置されている部材の表面積等を考慮し、主要経路120や導入経路12A〜12Dに用いる配管の径や、ポンプ12P,152A〜152Dの能力、導入バルブ12vA〜12vD、戻りバルブ153A〜153D、および循環用バルブ32A〜32Dの開度などを定めることができる。したがって、殺菌洗浄システム100により殺菌洗浄される区画A〜Dの一つあたりの所要時間を設定することが可能となる。
The amount, flow rate, and sterilization time of the required disinfectant are determined based on the predetermined sterilizing capacity required of compartments A to D.
In addition, it is necessary for cleaning so that the used disinfectant can be sufficiently washed away from the walls of compartments A to D, the members of the transport device, the filling valve, etc., or the concentration of the disinfectant can be lowered below the threshold value. The amount of water, flow rate, and cleaning time are determined.
Considering the size of each compartment A to D and the surface area of the members arranged in each compartment A to D so that a predetermined sterilizing ability and sufficient cleaning ability can be obtained for all the compartments A to D, etc. Determines the diameter of the piping used for the main path 120 and the introduction paths 12A to 12D, the capacity of the pumps 12P, 152A to 152D, the introduction valves 12vA to 12vD, the return valves 153A to 153D, and the opening degrees of the circulation valves 32A to 32D. be able to. Therefore, it is possible to set the required time for each of the compartments A to D to be sterilized and washed by the sterilization and cleaning system 100.
〔殺菌洗浄方法〕
以上で説明した殺菌洗浄システム100を用いて複数の区画A〜Dの殺菌および洗浄を行う方法を説明する。
(殺菌方法)
まず、図3を参照し、本実施形態の殺菌方法の手順の例について説明する。
図3(a)は、本実施形態の殺菌方法を示し、図3(b)は、比較例の殺菌方法を示している。
図3の左端に示した経過時間は一例に過ぎない。
[Sterilization cleaning method]
A method of sterilizing and cleaning a plurality of compartments A to D using the sterilization and cleaning system 100 described above will be described.
(Sterilization method)
First, an example of the procedure of the sterilization method of the present embodiment will be described with reference to FIG.
FIG. 3A shows the sterilization method of the present embodiment, and FIG. 3B shows the sterilization method of the comparative example.
The elapsed time shown at the left end of FIG. 3 is only an example.
比較例の殺菌方法は、図8(a)に示す構成を参照して説明したのと同様に、区画A〜Dのそれぞれの殺菌工程を順次行う。
具体的には、ポンプ102(図8(a))を作動させてタンク101から区画Aへと殺菌剤を供給(送液)することで区画Aの殺菌工程を開始し、所定の量だけ送液されたならば、タンク101へと液を戻すポンプ103も作動させて、区画Aとタンク101との間で殺菌剤を循環させる。そうした送液・循環のステップS81(図3(b))を所定時間に亘り行ったならば、ポンプ103により区画Aから殺菌剤を排出させ(排液)、タンク101に回収する(排液ステップS82)。次いで、区画Bの殺菌工程に移行し、区画Aからタンク11へと戻された殺菌剤を用いて送液・循環ステップS81を行い、それに続いて排液ステップS82を行う。以降は、区画C,Dについて順次、処理を繰り返す。
In the sterilization method of the comparative example, each sterilization step of the compartments A to D is sequentially performed in the same manner as described with reference to the configuration shown in FIG. 8 (a).
Specifically, the pump 102 (FIG. 8A) is operated to supply (send) a bactericidal agent from the tank 101 to the compartment A to start the sterilization process of the compartment A and send a predetermined amount. If liquid, the pump 103 that returns the liquid to the tank 101 is also operated to circulate the disinfectant between the compartment A and the tank 101. When the liquid feeding / circulation step S81 (FIG. 3B) is performed for a predetermined time, the bactericidal agent is discharged from the compartment A by the pump 103 (drainage) and collected in the tank 101 (drainage step). S82). Next, the process proceeds to the sterilization step of the section B, and the liquid feeding / circulation step S81 is performed using the disinfectant returned from the section A to the tank 11, and then the drainage step S82 is performed. After that, the processing is sequentially repeated for the compartments C and D.
要求される殺菌能力に基づいて、所定量の殺菌剤をある流量で一区画あたり散布すべき所要時間に、送液および排液に要する時間を加味すると、殺菌時間T1を定めることができる。区画A〜Dのそれぞれの殺菌工程を順次行うと、区画A〜Dの数の分だけ殺菌時間T1が積算される。 The sterilization time T1 can be determined by adding the time required for sending and draining the liquid to the time required for spraying a predetermined amount of the fungicide per section at a certain flow rate based on the required sterilizing ability. When each of the sterilization steps of the compartments A to D is sequentially performed, the sterilization time T1 is accumulated by the number of the compartments A to D.
一方、本実施形態では、図3(a)に示すように、区画A〜Dのうちの一の区画(例えばA)の殺菌工程の一部と並行して、他の区画(例えばB)の殺菌工程を行うので、工程処理時間が重なっている分、区画A〜Dの殺菌を短時間で終えることができる。
本実施形態の殺菌方法は、第1送液ステップA1と、第1自己循環ステップA2と、第1排液ステップA3と、第2送液ステップB1と、第2自己循環ステップB2と、第2排液ステップB3とを備えている。
一区画の送液ステップ(A1)、自己循環ステップ(A2)、および排液ステップ(A3)からなる殺菌工程に要する殺菌時間T1は比較例(図3(b))と変わらない。
On the other hand, in the present embodiment, as shown in FIG. 3A, in parallel with a part of the sterilization step of one of the compartments A to D (for example, A), the other compartment (for example, B) Since the sterilization step is performed, the sterilization of the compartments A to D can be completed in a short time because the process processing times overlap.
The sterilization method of the present embodiment includes a first liquid feeding step A1, a first self-circulating step A2, a first draining step A3, a second liquid feeding step B1, a second self-circulating step B2, and a second. It includes a drainage step B3.
The sterilization time T1 required for the sterilization step including the liquid feeding step (A1), the self-circulation step (A2), and the draining step (A3) in one section is the same as that of the comparative example (FIG. 3 (b)).
本実施形態に限らず、区画の容積や置かれた部材の表面積等に応じて、区画毎に異なる殺菌時間を設定することもできる。また、導入バルブ12vA〜12vD等のバルブの開度を区画毎に変えることもできる。 Not limited to this embodiment, different sterilization times can be set for each section according to the volume of the section, the surface area of the placed member, and the like. Further, the opening degree of the introduction valve 12vA to 12vD or the like can be changed for each section.
第1送液ステップA1では、供給ポンプ12Pを作動させてタンク11から第1区画Aへと殺菌剤を供給する。このとき導入バルブ12vA〜12vDのうち導入バルブ12vAのみを開いて残りは閉じておく。また、循環用バルブ32Aおよび戻りバルブ153Aも閉じておく。 In the first liquid feeding step A1, the supply pump 12P is operated to supply the disinfectant from the tank 11 to the first compartment A. At this time, of the introduction valves 12vA to 12vD, only the introduction valve 12vA is opened and the rest are closed. The circulation valve 32A and the return valve 153A are also closed.
区画Aへと所定量の殺菌剤が送られたならば、循環用バルブ32Aを開いて導入バルブ12vAを閉じることによって区画Aへの送液から自己循環に切り替えるとともに、導入バルブ12vBを開いて導入バルブ12vAを閉じることによって次の第2区画Bへの第2送液ステップB1を開始する。第2送液ステップB1は、第1送液ステップA1の開始に遅れることとなる。供給ポンプ12Pは引き続き作動させ、タンク11から主要経路120への送液を継続する。 When a predetermined amount of disinfectant is sent to the compartment A, the circulation valve 32A is opened and the introduction valve 12vA is closed to switch from the liquid supply to the compartment A to self-circulation, and the introduction valve 12vB is opened for introduction. By closing the valve 12vA, the second liquid feeding step B1 to the next second compartment B is started. The second liquid feeding step B1 is delayed from the start of the first liquid feeding step A1. The supply pump 12P is continuously operated to continue feeding the liquid from the tank 11 to the main path 120.
区画Aの第1自己循環ステップA2では、戻りポンプ152Aを作動させ、タンク11から第1区画Aへと所定量だけ供給された殺菌剤を、第1区画Aに与えられている自己循環系統3Aを通じて第1区画Aの内と外とを循環させる。
第1自己循環ステップA2の途中で、第2区画Bの送液ステップB1が終了し、循環用バルブ32Bを開いて導入バルブ12vBを閉じることによって第2区間Bの第2自己循環ステップB2に移行する。供給ポンプ12Pは停止させる。
この第2自己循環ステップB2は、第1自己循環ステップA2の開始に遅れ、第1自己循環ステップA2の一部と並行して行われる。
In the first self-circulation step A2 of the compartment A, the return pump 152A is operated, and a predetermined amount of the disinfectant supplied from the tank 11 to the first compartment A is supplied to the first compartment A in the self-circulation system 3A. The inside and outside of the first section A are circulated through.
In the middle of the first self-circulation step A2, the liquid feeding step B1 of the second section B is completed, and by opening the circulation valve 32B and closing the introduction valve 12vB, the process proceeds to the second self-circulation step B2 of the second section B. To do. The supply pump 12P is stopped.
The second self-circulation step B2 is delayed from the start of the first self-circulation step A2 and is performed in parallel with a part of the first self-circulation step A2.
図示されていない他の例として、第2自己循環ステップB2の時間が第1自己循環ステップA2の時間に対してかなり短いとすれば、ステップA2が行われている間に、ステップB2が開始し、そして終了する。このように、第1自己循環ステップと第2自己循環ステップとの長さが異なる場合であっても、それらの自己循環ステップが相互に一部において並行している。 As another example not shown, if the time of the second self-circulation step B2 is considerably shorter than the time of the first self-circulation step A2, the step B2 starts while the step A2 is being performed. , And finish. In this way, even when the lengths of the first self-circulation step and the second self-circulation step are different, the self-circulation steps are partially parallel to each other.
第1自己循環ステップA2の開始から殺菌に必要な所定時間が経過したならば、循環用バルブ32Aを閉じ、戻りバルブ153Aを開くことで自己循環を終了し、第1区画Aからタンク11へと殺菌剤を戻す第1排液ステップA3へと移行する。戻りポンプ152Aは引き続き作動させることができる。殺菌剤は、自重に加え、戻りポンプ152Aにより圧送されることで、タンク11へと戻される。なお、区画A内に溜まった水を自重のみで排出させることもできる。排液開始から所定時間が経過したならば、戻りポンプ152Aを停止する。 When the predetermined time required for sterilization has elapsed from the start of the first self-circulation step A2, the circulation valve 32A is closed and the return valve 153A is opened to end the self-circulation, and the process from the first section A to the tank 11 The process proceeds to the first drainage step A3 in which the disinfectant is returned. The return pump 152A can continue to operate. The bactericidal agent is returned to the tank 11 by being pumped by the return pump 152A in addition to its own weight. It is also possible to discharge the water accumulated in the compartment A only by its own weight. When a predetermined time has elapsed from the start of drainage, the return pump 152A is stopped.
第2区画Bについても、第2自己循環ステップB2の開始から所定時間が経過したならば、循環用バルブ32Bを閉じ、戻りバルブ153Bを開くことで自己循環を終了し、第2区画Bからタンク11へと殺菌剤を戻す第2排液ステップB3へと移行する。 Regarding the second compartment B, when a predetermined time has elapsed from the start of the second self-circulation step B2, the circulation valve 32B is closed and the return valve 153B is opened to end the self-circulation, and the tank from the second compartment B The process proceeds to the second drainage step B3 for returning the disinfectant to 11.
区画A〜Dを殺菌するにあたり、最初に殺菌を行う区画Aから最後に殺菌を行う区画Dまで、順次殺菌工程を開始しつつ、処理中の区画に対する自己循環のステップと、その処理に遅れた他の区画に対する自己循環のステップとを一部で並行させるのが好ましい。
一部並行処理により得られる時間短縮の観点に加え、殺菌剤の使用量を削減するために送液を開始するタイミングに配慮して、自己循環を一部並行して行う区画を定めることができる。図3(a)に示す例では、区画Aの自己循環ステップA2と区画Bの自己循環ステップB2とがオーバーラップし、区画Cの自己循環ステップC2と区画Dの自己循環ステップD2とがオーバーラップしている。
In sterilizing compartments A to D, the self-circulation step for the compartment being treated and the treatment were delayed while sequentially starting the sterilization process from the first sterilization compartment A to the last sterilization compartment D. It is preferable to partially parallel the steps of self-circulation with respect to other compartments.
In addition to the viewpoint of time reduction obtained by partial parallel treatment, it is possible to determine a section where self-circulation is partially performed in parallel in consideration of the timing of starting liquid feeding in order to reduce the amount of disinfectant used. .. In the example shown in FIG. 3A, the self-circulation step A2 of the compartment A and the self-circulation step B2 of the compartment B overlap, and the self-circulation step C2 of the compartment C and the self-circulation step D2 of the compartment D overlap. doing.
図3(a)に実線の矢印R1で示すように、区画Aから排出されてタンク11に戻ってきた液を他の区画Cへと供給することができる。つまり、区画Aが第1区画であり、区画Bが第2区画であるとすると、第1区画Aからの排液を第3区画である区画Cの殺菌に用いることができる。
その結果、自己循環ステップB2と自己循環ステップC2とがオーバーラップしなくても、自己循環ステップC2と自己循環ステップD2とをオーバーラップさせることができる。区画Dへの送液には、矢印R2で示すように、区画Bからの排液を用いることができる。
As shown by the solid arrow R1 in FIG. 3A, the liquid discharged from the compartment A and returned to the tank 11 can be supplied to the other compartment C. That is, assuming that the compartment A is the first compartment and the compartment B is the second compartment, the drainage from the first compartment A can be used for sterilization of the third compartment C.
As a result, even if the self-circulation step B2 and the self-circulation step C2 do not overlap, the self-circulation step C2 and the self-circulation step D2 can be overlapped. As the liquid is sent to the compartment D, the drainage from the compartment B can be used as shown by the arrow R2.
したがって、先に殺菌を終えた区画Aから排液が発生するタイミングに合わせて、他の区画Cへの送液を開始するとよい。具体的には、区画Bの自己循環ステップB2の途中で、区画Aの自己循環ステップA2から排液ステップA3へと移行したならば、区画Cに対応する導入バルブ12vCを開き、供給ポンプ12Pを作動させて区画Cへの送液を開始する。
区画Dについても、先に殺菌を終えた区画Bから排液が発生するタイミングに合わせて、送液を開始するとよい。
Therefore, it is preferable to start sending the liquid to the other compartment C at the timing when the drainage is generated from the compartment A that has been sterilized first. Specifically, if the self-circulation step A2 of the compartment A shifts to the drainage step A3 in the middle of the self-circulation step B2 of the compartment B, the introduction valve 12vC corresponding to the compartment C is opened and the supply pump 12P is started. It is activated to start pumping liquid to compartment C.
As for the compartment D, it is preferable to start the liquid feeding at the timing when the drainage is generated from the compartment B which has been sterilized first.
図3(a)に示す例では、矢印R1あるいはR2のように、第1区画AあるいはBからの排液が完了してから第3区画CあるいはDへの送液を開始しているが、一点鎖線の矢印で示すように、排液の完了を待つことなく、例えば、タンク11に規定量の殺菌剤液が戻ってきたことをトリガとして第3区画C,Dへの送液を開始することもできる。 In the example shown in FIG. 3A, as shown by arrows R1 or R2, the liquid is started to be sent to the third compartment C or D after the drainage from the first compartment A or B is completed. As shown by the arrow of the alternate long and short dash line, the liquid is started to be sent to the third compartments C and D, for example, triggered by the return of the specified amount of the disinfectant liquid to the tank 11 without waiting for the completion of the drainage. You can also do it.
殺菌を終えた区画からの排液を他の区画の殺菌へと用いると、図3(a)の左端に、タンク11に貯留されている殺菌剤の量を示すように、一区画の殺菌に使用される量の約2倍の量の殺菌剤をタンク11に用意しておけば、区画A〜Dの殺菌工程全体を通じて、各区画A〜Dへの送液に必要な殺菌剤を確保することができる。つまり、区画3つ分あるいは区画4つ分の殺菌剤をタンク11に用意する必要がない。 When the effluent from the sterilized compartment is used for sterilization of another compartment, one compartment is sterilized as shown by the amount of disinfectant stored in the tank 11 at the left end of FIG. 3 (a). If the tank 11 is prepared with about twice the amount of the disinfectant used, the disinfectant required for sending the liquid to each of the compartments A to D is secured throughout the disinfection process of the compartments A to D. be able to. That is, it is not necessary to prepare the disinfectant for three compartments or four compartments in the tank 11.
図3(a)に示す例では、区画A〜Dに同じ量の殺菌剤が供給されることを想定しているが、殺菌剤の供給量は区画A〜Dの間で異なっていてもよい。その場合は、殺菌を開始する区画A〜Dの順序を考慮し、タンク11内の殺菌剤が尽きることなく、区画A〜Dを殺菌する過程に亘り必要量を賄えるように、必要十分な量の殺菌剤を事前にタンク11内に確保するとよい。 In the example shown in FIG. 3A, it is assumed that the same amount of disinfectant is supplied to compartments A to D, but the supply amount of disinfectant may be different between compartments A to D. .. In that case, considering the order of the compartments A to D where sterilization is started, a necessary and sufficient amount is sufficient so that the necessary amount can be covered in the process of sterilizing the compartments A to D without running out of the disinfectant in the tank 11. It is advisable to secure the disinfectant in the tank 11 in advance.
図3(a)に示す本実施形態の殺菌方法において、一の区画の送液ステップ(例えばA1)と、他の区画の送液ステップ(B1,C1,D1)とは並行していない。また、一の区画の排液ステップ(例えばA3)と、他の区画の送液ステップ(B3,C3,D3)とは並行していない。
したがって、区画A〜Dのうちの2以上の区画に同時に送液されたり2以上の区画から排液されたりすることがなく、送液と排液に関してはあくまで順次行われることとなる。
そうすると、図8(b)に示す並行処理の場合とは異なり、2以上の区画への送液および2以上の区画からの排液に対応できる能力の大きいポンプ102´,103´や太い配管106,107が必要なく、図8(a)に示す順次処理の場合と同等の能力のポンプ12P,152A〜152Dを使用し、同等の径の配管を供給系統12の主要経路120や戻り経路151A〜151Dに使用することができる。これは、次に述べる洗浄方法についても同様である。
In the sterilization method of the present embodiment shown in FIG. 3A, the liquid feeding step (for example, A1) in one section and the liquid feeding step (B1, C1, D1) in the other section are not parallel to each other. Further, the drainage step (for example, A3) in one section and the liquid transfer step (B3, C3, D3) in the other section are not parallel to each other.
Therefore, the liquid is not sent to two or more compartments A to D at the same time or drained from the two or more compartments, and the liquid feeding and the drainage are performed sequentially.
Then, unlike the case of the parallel processing shown in FIG. 8B, the pumps 102'and 103' and the thick pipe 106 having a large capacity capable of sending liquid to two or more compartments and draining liquid from two or more compartments 106. , 107 are not required, and pumps 12P, 152A to 152D having the same capacity as in the case of sequential processing shown in FIG. 8A are used, and pipes having the same diameter are installed in the main path 120 and the return path 151A to the supply system 12. It can be used for 151D. This also applies to the cleaning method described below.
しかも、上述したように、殺菌を終えた区画(例えばA)から排液されてタンク11に戻ってきた液を他の区画(例えばC)へと供給することができるため、一区画の殺菌に使用される量の約2倍の液をタンク11に用意すれば足りる。そのため、図8(b)に示す並行処理の場合は各区画のそれぞれに使用される液量を合計した量の殺菌剤をタンク11に用意する必要があるのに対して、殺菌剤の使用量を削減してコストを抑えることができる。 Moreover, as described above, the liquid discharged from the sterilized compartment (for example, A) and returned to the tank 11 can be supplied to another compartment (for example, C), so that the sterilization of one compartment can be performed. It suffices to prepare about twice the amount of liquid used in the tank 11. Therefore, in the case of the parallel treatment shown in FIG. 8B, it is necessary to prepare the disinfectant in the tank 11 in the total amount of the liquids used in each section, whereas the amount of the disinfectant used is used. Can be reduced to reduce costs.
以上で説明したように、本実施形態の殺菌システム10および殺菌方法では、タンク11に殺菌剤を戻さずに自己循環系統3A〜3Dを通じて自己循環させるとともに、一の区画Aの自己循環ステップA2(また区画CのC2)と他の区画Bの自己循環ステップB2(または区画DのD2)とを一部並行して行うように、区画A〜Dのそれぞれの殺菌工程を時間的に前後にシフトさせている。そうすることで、区画Aの殺菌開始から区画Dの殺菌終了までに要する時間を抑えることができ、殺菌剤の使用量を削減することもできる。 As described above, in the sterilization system 10 and the sterilization method of the present embodiment, the sterilizing agent is not returned to the tank 11 but is self-circulated through the self-circulation systems 3A to 3D, and the self-circulation step A2 of one section A ( Further, the sterilization steps of the compartments A to D are shifted back and forth in time so that C2) of the compartment C and the self-circulation step B2 (or D2 of the compartment D) of the other compartment B are partially performed in parallel. I'm letting you. By doing so, the time required from the start of sterilization of the compartment A to the end of the sterilization of the compartment D can be suppressed, and the amount of the disinfectant used can be reduced.
自己循環系統3A〜3Dは、区画A〜Dから離間するタンク11を通らないので、自己循環系統3A〜3Dのそれぞれの経路長は、区画A〜Dのそれぞれとタンク11との間を殺菌剤が循環することを想定した場合の循環経路長と比べて短い。そのため、殺菌効力を得るために殺菌剤の加熱が必要な場合に、循環用経路31A〜31Dに最低限の規模でヒーターを設置しても、殺菌剤の温度が下がり難く、自己循環系統3を循環する間に亘り殺菌剤を所定の温度以上に維持することができる。 Since the self-circulation systems 3A to 3D do not pass through the tanks 11 separated from the compartments A to D, the respective path lengths of the self-circulation systems 3A to 3D are disinfectants between each of the compartments A to D and the tank 11. Is shorter than the circulation path length when it is assumed that Therefore, when it is necessary to heat the disinfectant in order to obtain the bactericidal effect, even if the heaters are installed in the circulation paths 31A to 31D on the minimum scale, the temperature of the disinfectant does not easily drop, and the self-circulation system 3 is used. The disinfectant can be maintained above a predetermined temperature during circulation.
(洗浄方法)
次に、図4(a)を参照し、本実施形態の洗浄方法の手順の例について説明する。
上述した区画A〜Dの殺菌工程を終えた後、区画A〜Dの壁や搬送装置の部材等に付着した殺菌剤を水によって洗い流す(すすぐ)ことができる。
殺菌後は、図2に示すように、供給系統12に液を供給する供給元をタンク11(図1)から水供給源21へと図示しないバルブの開閉等により切り替える。また、区画A〜Dから排水系統14A〜14Dへと水を導くため、戻りバルブ153A〜153D(図1)を閉じて排水バルブ141A〜141Dを開いておく。
(Washing method)
Next, an example of the procedure of the cleaning method of the present embodiment will be described with reference to FIG. 4A.
After completing the sterilization steps of the above-mentioned sections A to D, the sterilizing agent adhering to the walls of the sections A to D, the members of the transport device, and the like can be washed away (rinsed) with water.
After sterilization, as shown in FIG. 2, the supply source for supplying the liquid to the supply system 12 is switched from the tank 11 (FIG. 1) to the water supply source 21 by opening and closing a valve (not shown). Further, in order to guide water from the compartments A to D to the drainage systems 14A to 14D, the return valves 153A to 153D (FIG. 1) are closed and the drainage valves 141A to 141D are opened.
図4(a)は、本実施形態の洗浄方法を示し、図4(b)は、比較例の洗浄方法を示している。
比較例では、注水しながら区画A〜Dを順次洗浄する。
比較例では、水供給源から区画Aへとポンプにより新水を継続して送る(新水ステップS91)。ここで、「新水」は、未だ区画A〜Dには導入されていない水、つまり洗浄に供される前の水を言うものとする。
区画Aへと供給される新水は、ノズル12Nから区画A内へと散布される。その間、床に溜まった水を区画Aの外部へと排出し、新水の供給開始から所定時間が経過した後も、残存する水を区画Aの外部へと排出させる(排液ステップS92)。
所定時間の経過により区画Aの洗浄が完了したならば、ポンプを引き続き作動させて区画Bへの新水供給(S91)に移行することができる。以降、区画C,Dについて順次、同様の処理を繰り返す。
FIG. 4A shows a cleaning method of the present embodiment, and FIG. 4B shows a cleaning method of a comparative example.
In the comparative example, compartments A to D are sequentially washed while injecting water.
In the comparative example, fresh water is continuously pumped from the water supply source to the compartment A (new water step S91). Here, "new water" refers to water that has not yet been introduced into sections A to D, that is, water that has not been used for cleaning.
The fresh water supplied to the compartment A is sprayed from the nozzle 12N into the compartment A. During that time, the water accumulated on the floor is discharged to the outside of the compartment A, and the remaining water is discharged to the outside of the compartment A even after a predetermined time has elapsed from the start of the supply of new water (drainage step S92).
When the cleaning of the compartment A is completed after the lapse of a predetermined time, the pump can be continuously operated to shift to the fresh water supply (S91) to the compartment B. After that, the same processing is repeated sequentially for the compartments C and D.
区画A〜Dを十分に洗浄できるように、水をある流量で一区画あたり散布すべき洗浄時間T2が定められている。区画A〜Dを順次洗浄すると、区画A〜Dの数の分だけ洗浄時間T2が積算される。 A cleaning time T2 for spraying water at a certain flow rate per compartment is defined so that the compartments A to D can be sufficiently washed. When the compartments A to D are sequentially washed, the cleaning time T2 is accumulated by the number of the compartments A to D.
上記のように注水を続け、排水させながら、区画A〜Dを順次洗浄する比較例(図4(b))に対して、本実施形態では、図4(a)に示すように、区画A〜Dにそれぞれ供給された一定量の水を自己循環系統3の内部に留めて自己循環させ、さらに、一の区画の自己循環ステップ(例えばa2)の一部と並行して、他の区画の自己循環ステップ(例えばb2)を行う。これらの自己循環ステップが相互に並行して行われる時間の分だけ、区画A〜Dの洗浄を短時間で終えることができる。
区画A〜Dの数が多いほど、洗浄時間の短縮効果と水の使用量の削減効果とが大きい。
In contrast to the comparative example (FIG. 4 (b)) in which the compartments A to D are sequentially washed while continuing water injection and draining as described above, in the present embodiment, as shown in FIG. 4 (a), the compartment A A certain amount of water supplied to each of ~ D is retained inside the self-circulation system 3 and self-circulated, and further, in parallel with a part of the self-circulation step (for example, a2) of one compartment, in another compartment. Perform a self-circulation step (eg b2). Cleaning of compartments A to D can be completed in a short time by the amount of time these self-circulation steps are performed in parallel with each other.
The larger the number of compartments A to D, the greater the effect of shortening the washing time and the effect of reducing the amount of water used.
本実施形態の洗浄方法は、第1送液ステップa1と、第1自己循環ステップa2と、第1中間排液ステップa3と、第1仕上げ洗浄ステップa4と、第1排液ステップa5と、第2送液ステップb1と、第2自己循環ステップb2と、第2中間排液ステップb3と、第2仕上げ洗浄ステップb4と、第2排液ステップb5とを備えている。
ステップa1からステップa5までが第1区画Aの洗浄工程を構成し、ステップb1からステップb5までが第2区画Bの洗浄工程を構成している。
一区画に対する送液ステップa1、自己循環ステップa2、および仕上げ洗浄ステップa4のそれぞれの所要時間を合算した時間は、比較例(図4(b))の洗浄時間T2と変わらない。
The cleaning method of the present embodiment includes a first liquid feeding step a1, a first self-circulation step a2, a first intermediate drainage step a3, a first finish cleaning step a4, a first drainage step a5, and a first. The two liquid feeding step b1, the second self-circulation step b2, the second intermediate draining step b3, the second finishing cleaning step b4, and the second draining step b5 are provided.
Steps a1 to a5 constitute a cleaning step of the first section A, and steps b1 to b5 constitute a cleaning step of the second section B.
The total time required for each of the liquid feeding step a1, the self-circulation step a2, and the finish cleaning step a4 for one section is the same as the cleaning time T2 in the comparative example (FIG. 4B).
第1送液ステップa1では、供給ポンプ12Pを作動させて水供給源21から第1区画Aへと水を供給する。このとき導入バルブ12vA〜12vDのうち導入バルブ12vAのみを開いて残りは閉じておく。また、循環用バルブ32Aおよび戻りバルブ153Aも閉じておく。 In the first liquid feeding step a1, the supply pump 12P is operated to supply water from the water supply source 21 to the first section A. At this time, of the introduction valves 12vA to 12vD, only the introduction valve 12vA is opened and the rest are closed. The circulation valve 32A and the return valve 153A are also closed.
区画Aへと所定量の水が送られたならば、循環用バルブ32Aを開いて導入バルブ12vAを閉じることによって区画Aへの送液から自己循環に切り替えるとともに、導入バルブ12vBを開いて導入バルブ12vAを閉じることによって次の第2区画Bへの送液ステップb1を開始する。供給ポンプ12Pは引き続き作動させ、水供給源21から主要経路120への送液を継続する。 When a predetermined amount of water is sent to the compartment A, the circulation valve 32A is opened and the introduction valve 12vA is closed to switch from the liquid supply to the compartment A to self-circulation, and the introduction valve 12vB is opened to open the introduction valve. By closing 12vA, the liquid feeding step b1 to the next second section B is started. The supply pump 12P is continuously operated to continue the liquid supply from the water supply source 21 to the main path 120.
区画Aの第1自己循環ステップa2では、戻りポンプ152Aを作動させ、タンク11から第1区画Aへと所定量だけ供給された水を、第1区画Aに与えられている自己循環系統3Aを通じて第1区画Aの内と外とを循環させる。所定時間に亘り区画Aの内と外とを循環し、ノズル12Nから散布される水により、区画Aの壁や部材が洗い流される。 In the first self-circulation step a2 of the section A, the return pump 152A is operated, and a predetermined amount of water supplied from the tank 11 to the first section A is supplied to the first section A through the self-circulation system 3A. The inside and outside of the first section A are circulated. The walls and members of the compartment A are washed away by the water sprayed from the nozzle 12N, which circulates inside and outside the compartment A for a predetermined time.
第1自己循環ステップa2の途中で、区画Bの送液ステップb1が終了し、循環用バルブ32Bを開いて導入バルブ12vBを閉じることによって区間Bの自己循環ステップb2に移行する。供給ポンプ12Pは停止させる。
この自己循環ステップb2は、自己循環ステップa2の開始に遅れ、自己循環ステップa2の一部と並行して行われる。
In the middle of the first self-circulation step a2, the liquid feeding step b1 of the section B is completed, and by opening the circulation valve 32B and closing the introduction valve 12vB, the process proceeds to the self-circulation step b2 of the section B. The supply pump 12P is stopped.
This self-circulation step b2 is delayed from the start of the self-circulation step a2 and is performed in parallel with a part of the self-circulation step a2.
自己循環ステップa2の開始から洗浄に必要な所定時間が経過したならば、循環用バルブ32Aを閉じ、戻りバルブ153Aを開くことで自己循環を終了し、自己循環による洗浄に供された水を区画Aの外部へと排出させる中間排水ステップa3へと移行する。戻りポンプ152Aは引き続き作動させることができる。区画A内に溜まっている水は、自重に加え、戻りポンプ152Aにより洗浄システム20の外部へと排出される。なお、区画A内に溜まった水を自重のみで排出させることもできる。 When the predetermined time required for cleaning has elapsed from the start of the self-circulation step a2, the circulation valve 32A is closed and the return valve 153A is opened to end the self-circulation, and the water used for cleaning by the self-circulation is partitioned. The process proceeds to the intermediate drainage step a3 for discharging the water to the outside of A. The return pump 152A can continue to operate. The water accumulated in the compartment A is discharged to the outside of the cleaning system 20 by the return pump 152A in addition to its own weight. It is also possible to discharge the water accumulated in the compartment A only by its own weight.
区画Bについても、自己循環ステップb2の開始から所定時間が経過したならば、循環用バルブ32Bを閉じ、戻りバルブ153Bを開くことで自己循環を終了し、区画Bの外部へと水を排出させる中間排水ステップb3へと移行する。 As for the compartment B, when a predetermined time has elapsed from the start of the self-circulation step b2, the circulation valve 32B is closed and the return valve 153B is opened to end the self-circulation and drain the water to the outside of the compartment B. The process proceeds to the intermediate drainage step b3.
区画A〜Dが洗浄される過程で、区画A〜Cのいずれも第1区画に該当し、区画B〜Dのいずれも第2区画に該当する。
つまり、区画Aの自己循環ステップa2と区画Bの自己循環ステップb2とがオーバーラップし、区画Bの自己循環ステップb2と区画Cの自己循環ステップc2とがオーバーラップし、区画Cの自己循環ステップc2と区画Dの自己循環ステップd2とがオーバーラップしている。
In the process of cleaning the compartments A to D, all of the compartments A to C correspond to the first compartment, and all of the compartments B to D correspond to the second compartment.
That is, the self-circulation step a2 of the compartment A and the self-circulation step b2 of the compartment B overlap, the self-circulation step b2 of the compartment B and the self-circulation step c2 of the compartment C overlap, and the self-circulation step of the compartment C. c2 and the self-circulation step d2 of the compartment D overlap.
自己循環による洗浄、つまり、自己循環系統3の内部に留めた水により溜めすすぎを行った後、新水を供給して仕上げの洗浄を行う仕上げ洗浄ステップa4を行うことが好ましい。その後、区画A内の水を排出させる(排水ステップa5)。
仕上げ洗浄ステップa4は、新水を供給しつつ、排出させながら、区画Aの注水すすぎを行う。仕上げ洗浄ステップa4,b4,c4,d4は、互いに並行して行うことなく、順次行う。仕上げ洗浄ステップに続く排液ステップa5,b5,c5,d5も同様に、順次行う。
It is preferable to perform the finish cleaning step a4 in which the cleaning by self-circulation, that is, the water retained inside the self-circulation system 3 is used for pooling and rinsing, and then fresh water is supplied to perform the finishing cleaning. After that, the water in the compartment A is discharged (drainage step a5).
In the finish cleaning step a4, the water injection rinse of the section A is performed while supplying and discharging fresh water. The finish cleaning steps a4, b4, c4 and d4 are sequentially performed without being performed in parallel with each other. Similarly, the drainage steps a5, b5, c5 and d5 following the finish cleaning step are also sequentially performed.
自己循環による溜めすすぎを行うことで、壁や部材に付着した殺菌剤の濃度を十分に低下させておき、最後に、壁や部材の表面を新水を用いて洗い流すと、比較例のように注水すすぎのみを行う場合と比べて水の使用量を抑えながら、それと同等以上の洗浄効果を得ることができる。仕上げ洗浄は、必ずしも全ての区画A〜Dについて行う必要はなく、一部の区画については省略することもできる。
本実施形態の洗浄システム20および洗浄方法は、必ずしも区画A〜Dの殺菌後に使用される必要はない。殺菌剤が使用されていない場合にも、仕上げ洗浄に先立ち、自己循環による洗浄を行うことが、節水および洗浄効果向上に有効である。
By performing self-circulation and rinsing, the concentration of the disinfectant adhering to the walls and members is sufficiently reduced, and finally, the surface of the walls and members is washed away with fresh water, as in the comparative example. It is possible to obtain a cleaning effect equal to or higher than that while suppressing the amount of water used as compared with the case where only water injection rinsing is performed. The finish cleaning does not necessarily have to be performed for all the compartments A to D, and may be omitted for some compartments.
The cleaning system 20 and cleaning method of the present embodiment do not necessarily have to be used after sterilization of compartments A to D. Even when a disinfectant is not used, it is effective to save water and improve the cleaning effect by performing cleaning by self-circulation prior to finish cleaning.
区画Aの自己循環ステップa2後、区画Aへと新水を供給する仕上げ洗浄ステップa4、排液ステップa5および仕上げ洗浄ステップb4に移行することに優先して、他の区画C,Dの送液ステップc1,d1を開始することが好ましい。
そうすると、これらのステップc1,d1により区画C,Dにそれぞれ送り込まれた水を使って自己循環系統3C,3Dを通じて洗浄を進める間に(自己循環ステップc2,d2)、そのとき使われていない主要経路120を通じて区画A,Bへと新水を供給する仕上げ洗浄ステップa4,b4と、同じく使われていない排水系統14を通じて区画A,Bから水を排出させる排液ステップ(a5,b5)とを行うことができる。
After the self-circulation step a2 of the compartment A, the liquid feeding of the other compartments C and D is prioritized over the transition to the finish cleaning step a4, the drainage step a5, and the finish cleaning step b4 for supplying fresh water to the compartment A. It is preferable to start steps c1 and d1.
Then, while cleaning is carried out through the self-circulation system 3C and 3D using the water sent to the compartments C and D by these steps c1 and d1 (self-circulation steps c2 and d2), the main unused at that time is performed. Finish cleaning steps a4 and b4 for supplying fresh water to compartments A and B through the route 120, and drainage steps (a5 and b5) for draining water from compartments A and B through the same unused drainage system 14. It can be carried out.
つまり、流せる流量に限りのある供給系統12と排水系統14を効率よく使い、自己循環ステップc2,d2と、仕上げ洗浄および排液のステップa4,b4,a5,b5とを並行して行うことで、区画A〜D全体として洗浄時間を短縮することができる。
本実施形態では、区画Dへの送液ステップd1を終了した後すぐに区画Aに新水を供給する仕上げ洗浄ステップa4を行っており、図4(a)に矢印で示すように、水供給源21からの水の供給が間断なく継続される。つまり、供給ポンプ12Pを連続して作動させることができる。
That is, by efficiently using the supply system 12 and the drainage system 14 having a limited flow rate, the self-circulation steps c2 and d2 and the finish cleaning and drainage steps a4, b4, a5 and b5 are performed in parallel. , The cleaning time can be shortened for the entire compartments A to D.
In the present embodiment, a finish cleaning step a4 for supplying fresh water to the compartment A is performed immediately after the liquid feeding step d1 to the compartment D is completed, and water is supplied as shown by an arrow in FIG. 4 (a). The water supply from the source 21 is continued without interruption. That is, the supply pump 12P can be continuously operated.
区画A,Bの仕上げ洗浄ステップa4,b4を開始するタイミングは、仕上げ洗浄ステップa4,b4,c4,d4同士が並行しないように、かつ、排液ステップa5,b5,c5,d6同士が並行しないように定めている。
但し、図4(a)に斜線で示した時間の分だけ、自己循環ステップa2,b2を延長したり、仕上げ洗浄ステップa4,b4を早期に開始してもよい。
The timing of starting the finish cleaning steps a4 and b4 of the compartments A and B is such that the finish cleaning steps a4, b4, c4 and d4 are not parallel to each other and the drainage steps a5, b5, c5 and d6 are not parallel to each other. It is stipulated as follows.
However, the self-circulation steps a2 and b2 may be extended or the finish cleaning steps a4 and b4 may be started early by the time indicated by the diagonal lines in FIG. 4A.
仕上げ洗浄ステップa4,b4,c4,d4では、自己循環系統3を通じて水を循環させながら洗浄したり、自己循環と、注水による洗浄とを組み合わせることもできる。自己循環系統3を通じて水が循環している間は、他の区画への送液や排液の処理を進めることができる。 In the finish cleaning steps a4, b4, c4 and d4, cleaning can be performed while circulating water through the self-circulation system 3, or self-circulation and cleaning by water injection can be combined. While the water is circulated through the self-circulation system 3, it is possible to proceed with the process of sending and draining the liquid to another section.
(洗浄方法の変形例)
図5に示す変形例では、自己循環ステップa2を終えた後、区画Aから水を排出させる処理(図4(a)のステップa3)を行うことなく、新水を区画Aに供給する仕上げ洗浄ステップa4を行う。他の区画B〜Dについても同様である。このようにしても、溜めすすぎの効果が得られる自己循環洗浄後に、新水が供給されるため、殺菌剤の濃度を許容値以下に下げることができる。
(Modified example of cleaning method)
In the modified example shown in FIG. 5, after the self-circulation step a2 is completed, the finish cleaning for supplying fresh water to the compartment A without performing the treatment of discharging water from the compartment A (step a3 in FIG. 4A). Step a4 is performed. The same applies to the other compartments B to D. Even in this way, since fresh water is supplied after the self-circulating washing in which the effect of pool rinsing is obtained, the concentration of the bactericidal agent can be lowered to the allowable value or less.
送液を伴う仕上げ洗浄ステップa4,b4,c4,d4同士が並行したり、その後の排液ステップa5,b5,c5,d5同士が並行したりしないように、これらの送液・排液を区画A〜Dの間でシフトさせている。図5に示す例のように、自己循環ステップa2,b2,c2,d2をそれぞれ、一点鎖線以下に示すように延長して行ってもよい。この例では、区画Aの送液ステップa1の開始時から、区画Dの送液ステップd4の終了時まで、供給ポンプ12Pを連続して作動させている。 The liquid feed / drainage is partitioned so that the finish cleaning steps a4, b4, c4, d4 accompanied by the liquid feed are not parallel to each other, and the subsequent drainage steps a5, b5, c5, d5 are not parallel to each other. It is shifting between A and D. As in the example shown in FIG. 5, the self-circulation steps a2, b2, c2, and d2 may be extended as shown below the alternate long and short dash line, respectively. In this example, the supply pump 12P is continuously operated from the start of the liquid feeding step a1 in the compartment A to the end of the liquid feeding step d4 in the compartment D.
以上で説明したように、本実施形態の殺菌洗浄システム100によれば、複数の区画A〜Dを殺菌および洗浄するにあたり、区画A〜Dへの送液や区画A〜Dからの排液は順次行いながら、区画A〜D毎に与えられた自己循環系統3を用いる自己循環を並行して行うことにより、殺菌剤および水の使用量を抑えつつ、殺菌および洗浄に要する時間を短縮することができる。 As described above, according to the disinfectant cleaning system 100 of the present embodiment, when sterilizing and cleaning a plurality of compartments A to D, the liquid sent to the compartments A to D and the drainage from the compartments A to D are removed. By sequentially performing self-circulation using the self-circulation system 3 given to each of the sections A to D in parallel, the time required for sterilization and cleaning can be shortened while suppressing the amount of disinfectant and water used. Can be done.
〔殺菌洗浄システムの製造方法〕
本実施形態の殺菌洗浄システム100(図1)を製造する方法の一例を説明する。
タンク11と、区画A〜Dとを用意する工程S1と、供給系統12を設置する工程S2と、戻り系統15を設置する工程S3と、区画A〜Dにそれぞれ自己循環系統3を与える工程S4とを実施すると、殺菌洗浄システム100を構成する殺菌システム10(図1)が製造される。

[Manufacturing method of sterilization cleaning system]
An example of a method for manufacturing the sterilization cleaning system 100 (FIG. 1) of the present embodiment will be described.
Step S1 for preparing the tank 11 and compartments A to D, step S2 for installing the supply system 12, step S3 for installing the return system 15, and step S4 for providing the self-circulation system 3 to the compartments A to D, respectively. When the above is performed, the sterilization system 10 (FIG. 1) constituting the sterilization cleaning system 100 is manufactured.
The supply system 12 is installed by assembling the supply pump 12P, the main path 120, the introduction paths 12A to 12D, the introduction valves 12vA to 12vD, and the like.
The return system 15 is installed by assembling the return paths 151A to 151D, the return pumps 152A to 152D, the return valves 153A to 153D, and the like.
The self-circulation systems 3A to 3D are installed by assembling circulation paths 31A to 31D, circulation valves 32A to 32D, and the like.
一方、洗浄システム20(図2)は、複数の区画A〜Dを用意する工程s1と、水供給源21から水を供給する供給系統12を組み上げて設置する工程s2と、排水系統14を組み上げて設置する工程s3と、区画A〜Dにそれぞれ自己循環系統3を与える工程s4とを実施することで製造される。
主要経路120と水供給源21とを繋ぐ配管を施工し、排水系統14A〜14Dを戻り経路151A〜151Dに組み付ければ、殺菌洗浄システム100が完成する。
自己循環系統3A〜3Dは、殺菌システム10の自己循環系統3A〜3Dと全体の構成が共通しているため、追加の施工は不要である。
On the other hand, the cleaning system 20 (FIG. 2) includes a step s1 for preparing a plurality of compartments A to D, a step s2 for assembling and installing a supply system 12 for supplying water from the water supply source 21, and a drainage system 14. It is manufactured by carrying out the step s3 of installation and the step s4 of providing the self-circulation system 3 to the compartments A to D, respectively.
The sterilization cleaning system 100 is completed by constructing a pipe connecting the main route 120 and the water supply source 21 and assembling the drainage systems 14A to 14D to the return routes 151A to 151D.
Since the self-circulation systems 3A to 3D have the same overall configuration as the self-circulation systems 3A to 3D of the sterilization system 10, no additional construction is required.
〔殺菌洗浄システムの改造による製造方法〕
殺菌システム10、洗浄システム20、およびそれらを備えた殺菌洗浄システム100は、既存のシステムを改造することで製造することができる。
その場合は、殺菌システム10であれば、自己循環系統3を除いて、タンク11や区画A〜D、供給系統12、および戻り系統15が既に備わっているから、区画A〜Dに個別に自己循環系統3を与えるだけで足りる。
洗浄システム20も、やはり、自己循環系統3を除いて、水供給源21や区画A〜D、水供給源21からの水の供給系統12、および排水系統14が既に備わっているから、区画A〜Dに個別に自己循環系統3を与えるだけで足りる。
[Manufacturing method by modifying the sterilization cleaning system]
The sterilization system 10, the cleaning system 20, and the sterilization cleaning system 100 including them can be manufactured by modifying an existing system.
In that case, since the sterilization system 10 already has the tank 11, the compartments A to D, the supply system 12, and the return system 15 except for the self-circulation system 3, the compartments A to D are individually self-contained. It suffices to give the circulation system 3.
Since the cleaning system 20 also already includes the water supply source 21, the compartments A to D, the water supply system 12 from the water supply source 21, and the drainage system 14, except for the self-circulation system 3, the compartment A It suffices to give ~ D individually the self-circulation system 3.
上記の改造にあたり、供給ポンプ12Pや戻りポンプ152A〜152Dの更新、供給系統12や戻り系統15、排水系統14等の配管の付け替えは必要ない。
自己循環系統3は、各区画A〜Dの近くで取り回されるので、短い配管を組み上げて容易に設置することができる。
既存のシステムに自己循環系統3を付加するだけで、上述したように、区画A〜Dの殺菌や洗浄に要する時間を抑え、殺菌剤や水の使用量も抑えることができるので、製造効率を向上させることができる。
In the above modification, it is not necessary to update the supply pump 12P and the return pumps 152A to 152D, and to replace the piping of the supply system 12, the return system 15, the drainage system 14, and the like.
Since the self-circulation system 3 is routed near each of the sections A to D, short pipes can be assembled and easily installed.
By simply adding the self-circulation system 3 to the existing system, as described above, the time required for sterilization and cleaning of compartments A to D can be suppressed, and the amount of disinfectant and water used can also be suppressed, so that the production efficiency can be improved. Can be improved.
〔本発明の変形例〕
自己循環系統3は、必ずしも全ての区画A〜Dに個別に与えられる必要はない。例えば、区画Dには自己循環系統3が与えられていない場合でも、この区画Dに関しては、タンク11と区画との間で殺菌剤を循環させながら殺菌したり、水供給源21から水を供給しつつ排出させながら洗浄することが可能である。他の区画A〜Cの自己循環ステップを相互にオーバーラップさせる分だけ、区画A〜Dの殺菌や洗浄に要する時間を短くすることができる。
[Modification of the present invention]
The self-circulation system 3 does not necessarily have to be given to all compartments A to D individually. For example, even if the compartment D is not provided with the self-circulation system 3, the compartment D can be sterilized while circulating a disinfectant between the tank 11 and the compartment, or water can be supplied from the water supply source 21. It is possible to wash while discharging while discharging. The time required for sterilization and cleaning of compartments A to D can be shortened by the amount that the self-circulation steps of the other compartments A to C overlap each other.
本発明の殺菌方法または洗浄方法においては、上述のように、区画毎に備えられた自己循環系統3を利用して、一の区画と他の区画との間で自己循環ステップ同士をシフトさせつつ並行して行うほか、例えば、図6に示す殺菌方法のように、同一区画(例えばA)に係る自己循環ステップ(A2)と送液ステップ(A1)とを一部において並行して行うこともできる。その場合は、例えば、図7に示すように、適宜に配管やバルブを配置することにより、導入経路12Aを通じて区画Aへと送液する系統とは別に、区画Aへと液を戻すように自己循環系統3を構成するとよい。
図7に示す構成によれば、区画Aに関し、タンク11から導入経路12Aおよびノズル12Nを通じて送液しつつ、ポンプ152Aを作動させて、循環用経路31Aおよびノズル33Nを通じて液を循環させることができる。
ここで、タンク11から導入バルブ12vAを通じて送液している間にはバルブ34vAを閉じて、戻りポンプ152Aにより区画Aに殺菌剤を循環させる。そうすると、供給ポンプ12Pによる流れと戻りポンプ152Aによる流れとの干渉により供給ポンプ12Pによる送液圧力が低下することを防止できる。
図6に示すように、区画Aへの送液(ステップA1)の途中で、循環可能な量だけ区画Aに供給されたならば、自己循環ステップA2に移行することができる。したがって、ステップA1とステップA2とがラップする分だけ、より一層時間短縮を図ることができる。
In the sterilization method or the washing method of the present invention, as described above, the self-circulation system 3 provided for each compartment is used to shift the self-circulation steps between one compartment and the other compartment. In addition to performing in parallel, for example, as in the sterilization method shown in FIG. 6, the self-circulation step (A2) and the liquid feeding step (A1) related to the same section (for example, A) may be performed in parallel in part. it can. In that case, for example, as shown in FIG. 7, by appropriately arranging pipes and valves, the liquid is returned to the compartment A separately from the system that sends the liquid to the compartment A through the introduction path 12A. The circulation system 3 may be configured.
According to the configuration shown in FIG. 7, the pump 152A can be operated to circulate the liquid through the circulation path 31A and the nozzle 33N while sending the liquid from the tank 11 through the introduction path 12A and the nozzle 12N. ..
Here, the valve 34vA is closed while the liquid is being sent from the tank 11 through the introduction valve 12vA, and the disinfectant is circulated in the compartment A by the return pump 152A. Then, it is possible to prevent the liquid feeding pressure by the supply pump 12P from dropping due to the interference between the flow by the supply pump 12P and the flow by the return pump 152A.
As shown in FIG. 6, in the middle of the liquid feeding to the compartment A (step A1), if a circulatory amount is supplied to the compartment A, the self-circulation step A2 can be started. Therefore, the time can be further shortened by the amount of lap between step A1 and step A2.
上記以外にも、本発明の主旨を逸脱しない限り、上記実施形態で挙げた構成を取捨選択したり、他の構成に適宜変更することが可能である。
上記実施形態で示した配管経路や、ポンプおよびバルブの配置等、具体的なシステムの構成は、本発明の主旨を逸脱しない限りにおいて適宜に改変することができる。
また、殺菌システム10および洗浄システム20は、必ずしも統合されている必要はなく、いずれも単体のシステムとして成立する。
In addition to the above, as long as the gist of the present invention is not deviated, the configurations listed in the above embodiments can be selected or changed to other configurations as appropriate.
Specific system configurations such as the piping path shown in the above embodiment and the arrangement of pumps and valves can be appropriately modified as long as they do not deviate from the gist of the present invention.
Further, the sterilization system 10 and the cleaning system 20 do not necessarily have to be integrated, and both are established as a single system.
